An Executive bill which, if the Parliament agrees to treat it as an emergency bill, is subject to a speedy legislative process. For example, all stages are taken in the Parliament rather than in committee, and the usual requirements for intervals between stages do not apply.

A measure that is passed to take effect immediately upon signing by the Governor or some other date (less than 90 days) as specified in the Bill. Bills introduced in the second year of the biennium must be of an emergency nature (except for budgetary matters).

Generally, this is a measure that, due to some exigency is passed to take effect immediately upon signing by the Governor or to take effect on some other date specified in the bill which is earlier than 90 days following final adjournment. Emergency bills require an affirmative vote of two-thirds of the elected members in each chamber to be enacted. In order to introduce a bill in the second regular session (except bills containing certain budgetary matters, etc.), it must be determined to be of an emergency nature (Constitution of Maine, Article IV, Part Third, Section 1). Such a measure, while it addresses an emergency, is not generally referred to as an emergency bill and does not require a two-thirds vote for enactment.

An Executive bill which, subject to the Parliament's agreement, undergoes a speeded-up legislative process. For example, all Stages are considered by the whole Parliament rather than by a specific committee, and the usual requirements for intervals between Stages do not apply (rule 9.21).
